package/qemu: separate user and system arch on powerpc64le

Browse Source 
QEMU provides a single system emulator that supports both powerpc64
and powerpc64le with a target called 'ppc64-softmmu', but it provides
a different usermode emulator for each one (with targets
'ppc64le-linux-user' and 'ppc64-linux-user').

Due to this asymmetry it is not possible to support both cases with
the single arch value used in the package file. This patch introduces
an additional value into the package configuration,
HOST_QEMU_SYS_ARCH, so that both cases can be supported.

Fixes commit d2ff457e88
and autobuilder failture
